A low-mass star has been discovered racing through the Milky Way at over a million miles per hour, a journey that began with either the supernova explosion of a vampire star or an encounter with black holes.

Fast radio bursts erupt in the sky around 10,000 times a day, but scientists still struggle to explain them. New research could put astronomers one step closer to a solution.

Two million years ago, an encounter with a cold cloud of gas and dust could have caused our planet's "protective giant bubble" to draw back, potentially cooling our planet, new research claims.

Stephen Hawking suggested nothing lasts forever, including black holes. Scientists may have a way to prove it at last.

New research shows that a planet spotted around the real-life star 40 Eridani A, famous for hosting Dr. Spock's fictional home world in 'Star Trek', may have been an optical illusion all along.

The exoplanet Gliese 12 b is tantalizingly close and moderately warm, situated just 40 light-years away around a red dwarf star. The potentially habitable planet could be a good place to search for alien life, scientists say.

Researchers using NASA's Chandra X-ray telescope have found that a group of "Death Star black holes are swiveling around and pointing at new targets, like the fictional space station in Star Wars."

Scientists have calculated the speed of a spinning supermassive black hole by studying the 'spaghettified' remains of a star it destroyed.

Huge "tiger stripe" fault lines seen on Saturn's moon Enceladus raise hopes that a "long-lived" ocean containing potential alien life may lurk beneath the moon's icy shell.

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

An explosive flare from the Milky Way's central black hole has been translated from 'a single flickering pixel' into a detailed 3D model using AI and Einstein's general relativity equations.

JWST's surprise discovery of methane emissions and likely aurorae over a distant brown dwarf could indicate this "failed star" is orbited by an active moon.

"For the first time, we have physical evidence showing us what was happening in the moon's interior during this critical stage of its evolution, and that's really exciting."

Two projects using the James Webb Space Telescope will look at the auroras of Uranus and Saturn to discover what processes make them tick.

Recent observations show that some white dwarf stars suddenly stop cooling. Now, scientists propose a 'fountain of youth' mechanism that may explain how these stellar husks avoid death for billions of years.

A stunning new map of the magnetic fields at the Milky Way's center charts never-before-seen features, and raises new questions about how our galaxy's central engine works.

The ancient obect Gz9p3, which appeared as a single point of light through the Hubble Space Telescope, is actually one of the most enormous galaxies in the early universe, James Webb Space Telescope observations reveal.

The beloved James Webb Space Telescope will soon begin working on a fascinating to-do list for 2024 and 2025, including research into black holes, alien moons, dark energy and more.

New observations with the James Webb Space Telescope reveal that dwarf galaxies in the early universe released enough collective radiation to change the cosmos forever.

NASA's DART spacecraft seems to have completely reshaped asteroid Dimorphos after violently crashing into it in Sept. 2022

A neutron star spotted by the James Webb Space Telescope stayed hidden for 37 years while lurking in the wreckage of a stellar explosion, Supernova 1987A.

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another.

The discovery or an ultra-tiny white dwarf could reveal how stars smaller than Jupiter are born.

A meteor that exploded over Germany on Jan. 21 was confirmed to be a rare aubrite, a type of asteroid as old as the solar system.
